4 Claims.

This invention relates to a knitting machine yarn carrier having a feed tube for laying yarn along sinkers of a usual knitting head, and the primary objects of the invention are to minimize damage to the feed tube or sinkers and to facilitate replacement of a damaged or worn feed tube.

In accordance with my invention, a feed tube is normally held laterally by the jaws of a carrier finger and is normally positioned axially in such jaws by a springor rod which is pivotally connected to the finger and movable lengthwise thereof for attachment thereto or detachment therefrom.

The spring is preferably attached to the finger by a pin and slot connection and tends to bias the tube, away from the finger when the jaws are sprung by impact of the tube with an obstruction or by manual manipulation of the tube or Jaws.

The principles of my invention and the best mode in which I have contemplated applying such principles will further appear from the following description and the accompanying drawings in illustration thereof.

In the drawings, Fig. 1 is a fragmentary View of a yarn carrier embodying my invention and of a small portion of a knitting head in connection with which the yarn carrier is used; Fig. 2 is a side elevation of my improved yarn carrier indicating the several positions of the feed tube; Fig. 3 is a side elevation of my improved yarn carrier with the feed tube in yarn-laying position; Fig. 4 is a side elevation of my improved yarn carrier with the feed tube and spring detached from the body; Fig. 5 is a front elevation, looking in the direction of the line 5-5 of Fig. 4, of the feed tube and spring; Fig. 6 is a front elevation, looking in the direction indicated by the line 6-6 of Fig. 4, of the finger of my improved carrier with a phantom indication of the position of the feed tube and spring in the first step of attaching it to the carrier finger; Fig. '7 is a transverse sectional view taken on the line 1-? of Fig. 2; Fig. 8 is a transverse sectional View taken on the line 8-8 of Fig. 3 and Fig. 9 is a longitudinal sectional view taken on the line 9-9 of Fig. 6.

In the form of my invention illustrated in the drawings, my improved yarn carrier comprises a finger l having a head 2 and a foot 3 which is bent at an angle downward from the body of the finger and is bifurcated to form spring jaws 4 spaced from one another by an aperture 5. The jaws 4 contain concave seats 5 which extend somewhat more than half a circle around a feed tube 6. The feed tube 6 is normally springgripped by the jaws 4 and is mounted upon a leaf spring 1 which contains an opening 8 affording access to the bore of the tube 6. The upper end of the spring contains a bayonet slot 9 by which the spring can be slipped over the head It] and around the shank ll of a pin set in the finger I intermediate the ends thereof. The head It! contains a diametral opening l2 forming a guide for yarn passing from the usual tension members down over the spring 1 and through the bore of the feed tube 6 to the sinkers A of a usual knitting head. The spring 1 contains a curve 13 to facilitate its flexure around the bend between the body and jaws of the finger I so that the feed tube 6 may be snapped between and retained by the jaws 4, but is biased away from the jaws when released therefrom.

The head 2 contains apertures I4 for the attachment of the carrier to the holder of a carrier rod (not shown) in the usual manner.

The carrier is reciprocated over the sinkers A in back of the needles B, and the dividers C are then projected by the catch bar to loop the yarn X around the needles B as indicated in Fig. 1. If for any reason the sinkers should not be withdrawn from the path of the feeder tube 6, before the next traverse thereof, so that the tube strikes against the nose of a sinker, the impact causes an outward pressure on the tube 6 and therethrough on the jaws 4 which causes the jaws to release the tube and the resilient spring 1 springs the tube from between the jaws 4 out of range of the sinkers, as indicated in Fig. 2. Ordinarily the tube 6 will be projected from the jaws 4 without material damage to the sinker engaged thereby or to the tube, but, if the initial sinker is damaged, the remaining sinkers are undamaged. If the tube should be damaged by a smash, or if it is desired to replace the tube due to wear, or other cause, the tube may be snapped out of the jaws and the spring I slid lengthwise along the finger l until the head Ii] reaches with the large part of the opening 9 so that the spring can be removed from the pin and replaced with a similar spring and tube rapidly and accurately and without the necessity of using tools.

Having described my invention, I claim:

1. A knitting machine yarn carrier comprising a finger, jaws on said finger adjacent to an end thereof, a leaf spring, a tube on said spring and engaged by said jaws, and a headed member detachably connecting said spring with said finger above said tube.

2. A knitting machine yarn carrier comprising slotted spring receiving said member, and a feed tube connected with said finger and spring. 7 3. A knitting machine yarn carrier comprising a feed tube, a finger, separable jaws on said finger yieldingly gripping said tube, and a spring fixed to and biasing said tube away from said finger.

4. A knittingmachine yarnearrier comprising a feed tube, a .finger yieldingly gripping -?said tube, and a leaf spring fixed to said tube and RAYMOND J. GGOD.
